"Toshiba, the distant third vendor in the storage industry, was given the chance to buy part of Western Digital's hard drive business when it wanted to appease regulatory bodies to approve its purchase of Hitachi. With some of Western Digital's plants, Toshiba is now set to launch a range of 3.5in hard drives topping out at 3TB."

Before you go running out and buying the Western Digital Caviar Green 3 TB HDD, there are a few caveats to remember. You will not be able to just pop this into a WinXP machine and expect to use it at full capacity, you need to have a motherboard with UEFI in order to boot from it and finally the implementation of Advanced Format Technology is still stuck in 512-byte emulation mode.

On the plus side, the drive spins at about 6600 RPM and is SATAS 6Gbs which makes it faster that it's smaller predecessor. Only the non-AFT version of the 2TB Green drive can beat it for throughput. Check out the full review at TechARP.

"Western Digital divides their internal hard drives into three distinct families - the WD Caviar Blue for their basic hard drives, the WD Caviar Green for their quieter, cooler hard drives and the WD Caviar Black for their performance-grade hard drives.

According to Western Digital, Caviar Green hard disk drives offer an average power saving of 4-5 watts over their competitors, a feat that they claim is equivalent to reducing CO2 emissions by 13.8 kg per year. Of course, that’s a mere drop in the ocean but if you can help save the environment while you work or play on your computer, why not?

Today, we will look at the improved Western Digital Caviar Green 3 TB hard disk drive - the new Western Digital WD30EZRX with Advanced Format Technology and 6 Gbps interface. Let’s find out how well this drive performs!"
